My sisters son is 14, has an Xbox in his room. My sister will get up for a wee at 1.30am and he’ll still be playing his Xbox. This aside, he’s a really good kid, academically he’s doing so well and the late nights aren’t yet affecting his school work, he’s not even grumpy at home but DS wants to limit Xbox time, surely there is something you can do on the Xbox to set a timer or something similar to parental control?
